By putting in all the numerical values into the Boltzmann Equations and solving them, we show an asymmetric DM candidate \(N_1\)  being populated by
co-genesis of asymmetry in both visible and dark sectors. The model allows for a
DM mass range from a few MeV to TeV scale. As the mass range is wide, it allows
experimental and observational data from astrophysics, cosmology, and colliders
to constrain the framework's parameter space. The constraints imposed on heavier
mass DM(\(>\) TeV) are already well-known and can be referred
from [1]}. The mass of scalar singlet \(\phi \)  needs to be
greater than the mass of \(N_1\) , so as to not provide a second DM candidate. Thus
this puts a lower mass limit of \(\sim \text{TeV}\)  for \(\phi \) . The relic abundance
of DM would contain the contribution from \(\overline{N}_{1}\)  DM component as well, but as the
asymmetry in Dark Sector is of the order of \(10^{-10}\) , such a contribution
is negligibly small and can be safely ignored. In here, as also provided in
reference [2]}, there can exist interesting cosmological
consequences depending on the mass range of \(\phi \)  singlet. Using [3]}, [4]}, we see that the only constraint required from BBN in a model with extra singlet scalar is the fast decay of \(\phi \)  into SM states to avoid late dissociation processes, but as there is no interaction of \(\phi \)  with SM particles in our framework, so such a constraint is evaded here. The nucleon-scalar\((\phi )\) 
elastic scattering cross section can be also obtained for a parameter space
region and compared with the current limits for WIMP
searches [5]}. The presence of a singlet scalar means that any
real or virtual Higgs production would frequently be associated with \(\phi \) 
production, potentially leading to strong missing energy
signals [6]}. Any scalar portal mixing for a singlet scalar
\(\phi \)  from a term like \(\kappa _{\phi } (H^\dagger H)\phi \)  in the
lagrangian REF  is suppressed by considering \(\kappa _\phi \)  to be
negligibly small. As this is a scalar singlet extended SM framework, the
constraints from astrophysics are generally less severe compared to a framework
with SM extended with a \(U(1)\)  gauge group since a hidden photon couple to electric charge and therefore equally to electrons and protons, but
this can be avoided in a scalar extended framework.
